Type in the British Museum. 



This species is the Pecten asperrimus of New Zealand con- 

 chologists. According to Bavay it stands nearest to P. aktinos 

 ( = bednalli, Tate), and also shows some affinity with P. bi- 

 frons, Lamk. ( = tasmanicus, Ad. and Ang.) and P. lividus, 

 Lamk. ( = tegula, Wood). 



P. gemmuiatus, Reeve, is in my opinion an intermediate 

 form between P. zelandice, Gray, and P. imparvicostatus, Bavay. 

 The upper valve shows more or less characters of P. asperri- 

 mus, Lamk., but the lower valve is very different, and it never 

 attains the size of the latter. 



Mytilus canaliculus, Martyn (1784). 

 Mytilus canaliculus, Martyn, Univ. Conch., vol. ii, 1784, fig. 78. 



Mytilus latus (novce-zeelandice), Chemnitz, Conch. Cab., vol. 



viii, 1785, p. 167, pi. lxxxiv, fig. 747. 



As Chemnitz is not binomial in vol. viii, we have to use 

 Martyn' s name, which, moreover, has priority. Although his 

 figure is said to be not very good, yet he states that the 

 specimen came from New Zealand, and it is undoubtedly, as I 

 am also assured by Mr. Hedley, the same species as Chemnitz's 

 M. latus. 



Cardita calyculata, Linne (1767). 



Chama calyculata, Linne, Syst. Nat., 1767, p. 1138 ( = Cardita 

 aviculina, Lamarck, 1819 ; C. excavata, Deshayes, 1852 ; 

 C. tasmanica, T. -Woods, 1876). 

 For full synonymy of the species see Pritchard and Gatliff, 



Proc. Roy. Soc. Victoria, vol. xvii (n. s.), 1904, p. 234. 



Venericardia corbis, Philippi (1836). 

 Cardita corbis, Philippi, Enum. Moll. Siciliae, vol. i, 1836, p. 55 



( = unidentata, Basterot). 



A Pliocene fossil of south Italy, found living in the Adri- 

 atic, Mediterranean, and off the Canaries, in deep water 

 (552 fathoms, "Challenger" Exped.).
